Plus the fact that a 1200 watt inverter is going to cost some serious money
and will have to be wired into the battery direct.
Now - having an inverter has other purposes as well so might be worth it to
power TV, VCR/DVD, Fans, etc..

Just hope you have at least one extra battery.

Not if it's the right size inverter.


The other consideration is that most home vacs draw 8-12 amps at 120
volts. That
would suck a 100 amp hour 12 volt battery down to nothing very quickly,
even
without figuring in the losses of he inverter. Bear in mind that you can't
even
use all 100 amp hours of that battery. You can use about half of it before
you
need to stop and recharge. So, you've got 50 amp hours at 12 volts
powering
something that draws 10 amps at 120 volts. Doesn't sound very prudent just
to
suck up some wet sand and dust that could be swept up using no power at
all in
the same amount of time with MUCH cheaper equipment.

why not get a 12 DC to 120 AC inverter and vacuum away?



You may overload the converter doing this
